Mile by mile and person by person, North Korea is the most destabilizing nation on earth. The small, poor and isolated country is building nuclear weapons and intercontinental missiles. Americans who once felt invulnerable are worrying about the possibility of nuclear war.

Military action could trigger a destructive war, sanctions might do nothing or trigger regime collapse, and negotiations aren’t likely to result in the Korean Peninsula’s denuclearization.
